above indicated purpose, which will permit of using the same machinery for the purpose of regulating the speed, either of the customary note-disk or of the talking machine record.

rIhe features of my invention will appear from the description hereinafter following and from the appended claims.

Reference is to be had to the, accompanying drawings, in which Figure l is a plan of a music box embodyf ing my invention illustrated in condition for use as a talking machine Fig. 2 is a sectional elevation on line 2 2 of Fig. 3; Fig. 3 is a sectional plan on line 3 3 of Fig. 2; Fig. 4 is a plan view showing another form of my invention; Fig. 5 is a horizontal section of the same; Fig. 6 is an elevation with parts in section substantially on line 6 6 of Fig. 5; Fig. 7 is a sectional elevation on line 7 7 of Fig. 6; and Fig. S is an enlarged detail section on line 8 8 of Fig. 3, and Fig. 9 is an elevation thereof looking from the right of FiO'. 8.

indicates the box containing the mechanism, and also serving to support in any suitable manner the horn B and the arm C carrying the reproducer D. These parts may be of any suitable construction. The reproducer is adapted to rest on the record E carried by a rotary supporting plate F and adapted to be rotated thereby so as to reproduce music, song or speech in the customary manner. The supporting plate F isl provided with a central downward projection F', having a clutch connection with a projection G upon a shaft G, which is one of the shafts of the music box motor. The clutch connection in the particular instance illustrated is formed by providing the lower end of the projection F with a conical seat and by tapering the upper end of the projection G correspondingly. The shaft G carries a worm-wheel G2 engaging a worm H on the shaft H, which also carries the governor H2. Furthermore, the governor-shaft has a projection H3, into the path of which normally projects a stop l. This stop is mounted on a shaft F, adapted to be rocked by means of a slide I2 engaging an arm I3 on the shaft. A spring I keeps the arm I3 against the slide I?. There is also provided a speed regulator, consisting of an arm H4, pivoted at H and provided'with a beveled portion Hs which is adapted to engage a brake member a secured to an arm Z) pivoted at c to a stationary portion of the instrument and maintainedin its normal position by a spring d. The brake member a is provided with a pad of felt or like material adapted to frictionally engage the disk H5 of the governor. By pressing down a handle H7, the arm H'1 will be rocked on its pivot HG so that the beveled portion Hg will be swung upward and will move the brake member a toward the disk H5 against the tension of the spring d. .The pad will thus engage the surface of the disk H5 and will act as a brake to regulate the speed of the instrument. It will be understood that by moving the stop l out of the path of the projection H3, the mechanism of the music box is released.

The shaft G is also provided with a pinion G3 engaging a gear-wlieel J/ on a shaft J, which also carries a pinion J2. This pinion meshes with a gear-wheel K on a shaft K, which gear-wheel is also in mesh with a spurgear L on the spring drum L. This spring drum is also formed with teeth L2 upon its face or end, and with these teeth is engaged a bevel pinion M/ secured to a shaft M, which also carries the drive-wheel M2, adapted to engage and rotate the note-disk. The winding device for the spring consists of a large gear-wheel L3 secured to the shaft L4 of the spring drum and meshing with a pini'on N/ on the winding shaft N. This shaft also carries a ratchet N 2 normally engaged by a rctaining pawl O, fulcruined at O. Instead of being spring-pressed, according to the usual construction, this pawl is operatively connected with an arm N 3 mounted on said shaft and having a slot N4 into which extends a pin O2 on the retaining pawl. Thus, when starting to wind the spring, the arm N 3, being in frictional engagement with the shaft or the ratchet by means of a pin N 5, will swing the pawl away from the ratchet N 2, and owing to this distinctive feature the disagreeable noise commonly produced when winding spring motors will be avoided. At the same time, however, as soon as the spring winding operation is stopped, the slight backward rotation given to the winding-shaft by the tension of the spring will cause the retaining pawl to be swung back into engagement with the ratchetvwheel.

The motor or driving mechanism arrangement hereinbefore described is exceedingly simple, and its operation is practically the same, whether thel motor is used to drive a note-disk or a talking machine record. In either event, the same starting and stopping mechanism is lused and the same speed regulating mechanism. It will be understood, of course, that the clutch section G of the shaft is exposed when the note disk is removed from the machine, and that this clutch section forms a carrier for the supporting plate F. l

The form of my invention illustrated by Figs. 1 to 7 inclusive diers from the one first described, chiefly by the fact that provision is made for driving the music disk from the center instead of peripherally and also in the details of the stopping and starting mechanism and the speed governor.

The rotary supporting plate 1 has a pin 2 to center the record and is provided with a downwardly projecting socket 3, preferably tapered as shown, which is adapted to receive a corresponding projection 4 upon the shaft 5, thus forming a friction clutch. The shaft 5 carries the pinion 6 and the wormwheel 7, which latter is in driving engagement with the worm8 on the shaft 9 of the governor 10. Any suitable governor may be employed. The particular one illustrated comprises an arm secured to the shaft 9 and pivotally carrying at its ends the governor blades 10 under the influence of springs 10a.

On the shaft 9 is mounted a projection 9a adapted to collide with the arrestingdevice as hereinafter explained. The pinion 6 is driven from a gear-wheel 11 mounted on a shaft 12 which also carries a pinion 13. This latter pinion is in mesh with a gear-wheel 14 on a shaft 15, which also carries another gear-wheel 16. Pinion 16 is in engagement with' the gear-wheel 17 on the drum 18. This drum contains the customary spring, one end of which is securedto said drum and the other to the shaft 19, on which the drum is loosely mounted.

The lwinding device comprises a large gear-wheel 2O secured to the shaft 19, and engaged by a pinion 21 on a winding-shaft 22. This shaft has secured to it rigidly a ratchet-wheel 23 and a pin 24, which latter holds an arm 25 in frictional engagement with suflicient force toI cause such arm to partly follow the winding-shaft in its rotation. The arm 25 has a slot 25EL which receives a pin 26";l projecting from the retaining pawl 26. Thus, when the operator starts winding the arm 25 will throw the pawl 26 away from the ratchet-wheel 23, so that the clicking Anoise caused by the pawl sliding over the ratchet teeth will be avoided. As soon as the operator releases the key used for turning the winding-shaft, the arm 25 will swing the pawl 26 inward to again engage the ratchet-wheel 23. This winding device is the same as has been described with reference to the i'irst form of my invention.

The upper end of the shaft 15 carries a support 27 for the note-disk, said support being provided with one or two eccentric pins 27a adapted to engage corresponding holes in the note-disk and to drive the same.

Two starting devices are preferably provided, either one of which is adapted to cooperate with the arm 9a. The starting device which is generally employed when the device is used as a music box comprises a lever 28 fulcrumed at 29, and adapted to project into the path of the arm 91a, as shown in Fig. 7, the lever being normally held in such position by a spring. This lever is provided with an arm 28a adapted to engage a portion of the drum 18, and to fall into a recess of said drum at a predetermined point. This construction is so Well known that T have not deemed it necessary to illustrate the details thereof. It will be understood that during the greater portion of the drunis revolution the projection 28a is swung so as to release the arm 9a, but at a point which corresponds to the end of a piece, the projection 28a will drop into the recess of the drum and thus bring about the stopping of the motor. In order to start the motor in this case a sliding rod 30 is employed, the end of which coperates with an inclined surface 28b of the lever 28.

When theapparatus is used as a talking machine, it is necessary that there should be a possibility of stopping the motor at any point.' For this purpose a starting rod 31 is employed, having an end portion 31EL adapted to project into the path of the arm 9a when such rod 31 Ais moved inward. 1t will be understood that during this use of the machine the rod 30 would be kept in its outer position so as to throw the lever 28 permanently out of action.

The speed may be regulated by means of an elastic brake .32 which is carried by an arm 33, fulcrumed at 34, and operated by means of a lever 35. This brake is adapted to swing against a spring-pressed collar 36, and by giving the lever 35 a greater or smaller throw the action of the brake and consequently the speed of the motor, may be regulated.

Various modifications may be made Without departing from the nature of my invention.

I claim as my invention:

In a music box, a governor shaft, a governor carried thereby a vertical sh aft in direct driving connection with the governor shaft,

' a holder for a note-sheet, and driving means for such sheet, said driving means being operatively connected With the said vertical shaft, and a removable support for a talking l l l machine record, carried by the upper end of said vertical shaft at a level above the notesheet holder.

In testimony whereof, I have signed my 15 name to this specification in the presence of two subscribing Witnesses.
